Description

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the bug

When running the aspire start command for a second time (or aspire restore), the creation of the .venv fails due to the .venv already existing.

### Expected Behavior

Work seamlessly

### Steps To Reproduce

Create a python apphost, run it twice or restore it twice on windows.

### Exceptions (if any)

error: Failed to create virtual environment
Caused by: Failed to create Python executable link at .venv\Scripts\python.exe from C:\....
Caused by: The file exists. (os error 80)

My project is on a different drive btw.
